How Do You Fix an Overheating Aircon?

An overheating air conditioner (aircon) can lead to inefficiency, damage to components, or even complete breakdowns if not addressed promptly. Here’s a step-by-step guide to fixing an overheating aircon:

Turn Off the Aircon Immediately

If your air conditioner is overheating, the first step is to turn it off. This will prevent further damage and give the system a chance to cool down.

Check the Air Filter

Dirty air filters are a common cause of overheating. Dust and debris restrict airflow, forcing the aircon to work harder and overheat.

  • Remove the air filter and inspect it for dirt buildup.
  • If it’s dirty, clean it with water and allow it to dry completely before reinstalling it. If it’s damaged, replace it.

Inspect the Outdoor Unit

The outdoor unit, or condenser, can overheat if it’s clogged with dirt, leaves, or other debris.

  • Turn off the power supply to the aircon.
  • Use a garden hose to gently clean the condenser fins. Avoid using high pressure, which could damage the fins.
  • Ensure there’s adequate space around the unit for proper airflow.

Check Refrigerant Levels

Low refrigerant levels can cause the air conditioner to overheat. If you notice ice forming on the evaporator coil or warm air blowing from the unit, it could indicate a refrigerant issue.

  • Contact a licensed HVAC technician to check and refill the refrigerant. Never attempt to do this yourself, as handling refrigerants requires specialized training.

Examine the Fan Motor

The fan motor helps dissipate heat from the condenser. If it’s malfunctioning, the aircon could overheat.

  • Listen for unusual noises or observe if the fan is running slower than usual.
  • If you suspect an issue, consult a professional to repair or replace the motor.

 Ensure Proper Ventilation

Poor ventilation in the room where the aircon is installed can cause it to work harder, leading to overheating.

  • Keep doors and windows closed when the aircon is running.
  • Remove any obstructions blocking the air vents.

 Inspect the Thermostat

A malfunctioning thermostat can cause the aircon to overwork, leading to overheating. Ensure the thermostat is functioning correctly and set to a reasonable temperature.

Schedule Regular Maintenance

Routine maintenance can prevent most overheating issues. Have a professional inspect and service your aircon at least once a year to ensure optimal performance.

When to Call a Professional

If the above steps don’t resolve the issue, or if you’re unsure about diagnosing or fixing the problem yourself, it’s time to call an HVAC technician. Attempting complex repairs without expertise can worsen the situation or void warranties.

By addressing overheating promptly and maintaining your aircon regularly, you can extend its lifespan and ensure it operates efficiently, even during the hottest days.
